ELECTRIC MACHINE

WIPO Patent Application WO/2013/110450

A3

Disclosed is an electric machine, in particular a transverse flux machine, wherein the stator is composed of a stack of phase segments, each of which includes at least one stator segment and a stator winding, especially a single winding. Each stator segment has an annular stator web, onto which pole shoes are molded. In particular, said pole shoes extend radially inward and/or in the direction of the rotor and/or are arranged between the rotor and the annular stator web. In particular, the pole shoes are similarly shaped, the axial width of the pole shoe decreasing as the radial distance increases. The associated shape lies between a first and a second shape, the first shape being a linear function of the radial distance, in particular the pole shoe rear that is part of the first shape being a flat surface, and the second shape being a circular function, in particular a circular sector function, in particular the pole shoe rear that is part of the second shape being a surface of a cylinder sector.
